Even mildly elevated air pollution associated with increase in absences in Salt Lake City — ScienceDaily

In Salt Lake City schools, absences rise when the air quality worsens, and it’s not just in times of high pollution or “red” air quality days — even days following lower levels of pollutions saw increased absences.

Research is still ongoing, and the evidence isn’t yet conclusive enough to draw a cause-and-effect relationship between air quality and children’s absences from school but the correlation, according to Daniel Mendoza, a research assistant professor in the Department of Atmospheric Sciences and visiting assistant professor in the Department of City & Metropolitan Planning, merits further exploration. Mendoza and his colleagues published their results in Environmental Research Letters.

Air pollution is harmful for not only the health, but also the education and well-being of children in our community,” says study co-author Cheryl Pirozzi, assistant professor in the Division of Respiratory, Critical Care, and Occupational Pulmonary Medicine. “Even at relatively low levels that many

PlanetCare’s Laundry Filter Helps Stop Ocean Plastic Pollution

Getting microplastics out of laundry

Illustrator: Cathryn Virginia

Mojca Zupan was a corporate lawyer doing just fine—“comfort-zone-fine,” as she puts it—in 2016, when a museum exhibit changed her life.

The Plastic Garbage Project depicts the “the origins, life cycle, sense, and senselessness of plastic products.” “I saw these big microscopic pictures of microfibers,” Zupan says of the tiny grains of plastic that slough off synthetic textiles and seep into bodies of water. “It’s ridiculous. Washing machines pollute so heavily.”

She did some research. Technically, a solution for catching microfibers existed. But awareness of the issue was low. “I didn’t get the feeling that something would be done about it in the near future,” Zupan says. “I became determined to change the washing machine industry.” Within a year, Zupan had started PlanetCare and begun selling the company’s first product, a filter that

Are China’s pollution remediation efforts making the planet warmer? China’s efforts to combat aerosol pollution resulted in warming throughout the northern latitudes — ScienceDaily

A 10-year effort by China to improve air quality and reduce pollution-related health risks has caused warming in areas across the northern hemisphere, according to new work published in Environmental Research Letters.

Aerosols are tiny particles that are spewed into the atmosphere by human activities, such as burning coal and wood, or by geological phenomena, like volcanos. Their negative effects on air quality can damage human health and agricultural productivity.

Similar to how the aerosols emitted in a volcanic eruption can cause global temperatures to drop, some aerosols from human activity also have a cooling effect on the climate. Unlike greenhouse gases, which induce global warming by trapping heat in the atmosphere, aerosol particles can cause sunlight to be reflected away from the planet either directly or by interacting with clouds.

“This means that some of the effects of global warming are being masked by aerosol pollution,” explained lead

Tree rings show scale of Arctic pollution is worse than previously thought — ScienceDaily

The largest-ever study of tree rings from Norilsk in the Russian Arctic has shown that the direct and indirect effects of industrial pollution in the region and beyond are far worse than previously thought.

An international team of researchers, led by the University of Cambridge, has combined ring width and wood chemistry measurements from living and dead trees with soil characteristics and computer modelling to show that the damage done by decades of nickel and copper mining has not only devastated local environments, but also affected the global carbon cycle.

The extent of damage done to the boreal forest, the largest land biome on Earth, can be seen in the annual growth rings of trees near Norilsk where die off has spread up to 100 kilometres. The results are reported in the journal Ecology Letters.

Norilsk, in northern Siberia, is the world’s northernmost city with more than 100,000 people,

First evidence that air pollution particles and metals are reaching the placenta — ScienceDaily

Pollution particles, including metals, have been found in the placentas of fifteen women in London, according to research led by Queen Mary University of London.

The study, funded by Barts Charity and published in the journal Science of The Total Environment, demonstrate that inhaled particulate matter from air pollution can move from the lungs to distant organs, and that it is taken up by certain cells in the human placenta, and potentially the fetus.

The researchers say that further research is needed to fully define the direct effect that pollution particles may have on the developing fetus.

Lead author Professor Jonathan Grigg from Queen Mary University of London said: “Our study for the first time shows that inhaled carbon particulate matter in air pollution, travels in the blood stream, and is taken up by important cells in the placenta. We hope that this information will encourage policy makers to

Scientists fight to protect orcas from man-made noise pollution

  • Experts are studying how man-made noise pollution, like from boats and oil drilling, is threatening the lives of orcas.
  • One team of scientists is collecting hundreds of hours of orca recordings off the coast of Norway in an effort to make to region a marine protected area.
  • Man-made noises interfere with orcas’ communication, which they use for hunting and mating.
  • And orcas trying to escape the underwater cacophonies may travel too far to the rocky shoreline, which can result in stranding and death.

  •  

Orcas have a language of their own. They communicate through touch, movement, and most importantly, sound.

And it’s marine scientist Ellyne Hamran’s job to eavesdrop on them. 

Hamran is an acoustic researcher studying the sounds marine mammals like whales and dolphins use to communicate. She’s captured hundreds of hours of orca recordings.

This summer, she’s listening to the
